Application filed July 2, 1918. Serial No. 242,992.

To all whom it may concern:

Be it known that I, ALFRED F. hIa'sURY, a citizen of the United States, residing in the borough of Manhattan of the city of New York, in the State of New York, have invented certain new and useful Improvements in Cooling Devices for Internal-Combustion Engines, of which the following is a specification, reference being had to the accompanying drawing, forming a part hereof.

' The object of this invention is to. promote a thorough circulation of the cooling water in the water jackets of internal combustion engines. Ordinarily the water from the radiator is admitted'to the water jacket at one side only of the engine and at a point higher than the bottom of the jacket. There is therefore a portion of the space within the Water jacket which is practically a dead a space in which a current as the result of the circulating means employed. In accordance with this invent-ion it is proposed to prevent the existence of such a dead water space by conducting a portion of the inflowing Water from a point near that at which it enters the water jacket, to 'a point at the opposite side of water jacket so that a portion of the inflowing water shall be directed into that space which would other- Wise be a dead water space and bring about the flow of the-water and the establishment of currents in all parts of the water jacket, whereby a more efficient action of the cooling Water is secured. The inventionwill be more fully explained hereinafter with reference to the accompanying drawing in which it is illustrated as applied to an internal combustion engine of usual construction, in connection with other improved features of the water circulating system which do not form part of the present invention. In the drawi-ng r t Figure 1 is a view in side elevation of an internal combustion engine equipped with the invention.

Fig. 2 is a partial view, partly in end elevation as seen from the right hand in Fig. 1 and partly in sectio The internal combustion engine I), i connection with which the invention is illustrated,-may be of any usual type of Water jacketed engines. It is shown in the drawthe engine and at or.

ing as having its four cylinders 7) arranged 111 blocks of two, water acketed as a;

through suitable pipes 0,0, with a common pump 7' from which water is delivered through a single outlet pipe 5/ and ln'anches g to the water jacket N, at one side there of, at points above the bottom, the water jacketing including at I), the inlet manifold. From the water jacket, at the top or head thereof, the heated water is delivered through outlet pipes h to a common equalizing tank II, which is suitably supported between the two radiators and is connected, at each end, through a suitable discharge pipe 7& with the corresponding radiator (Z.

In such an engine and without the present improvement the water delivered by the pump would naturally take the easiest and most direct path from the inlets 9 through the water jacket to the outlets h and as a. consequence the space near the bottom of the jacket and especially. at the opposite a dead water space, that is. a space in which the circulation of water is not influenced materially by the discharge from the circulating pump or other means relied upon to effect circulation. To prevent the existence of such a dead water space it is proposed, by the present invention, to conduct water from the inlet side of the water jacket, preferably from the jacketed portion of theinlet manifold, at 7):, to the water jacket at a point near the bottom and remote or opposite that at which the main flow of water enters the water jacket, as by a pipe or pipes external to the water jacket, connected to the water inlet, as at {7 and to the water jacket, as at As the purpose of this water connection is merely to.promote the movement of the water in the otherwise dead water space of the jacket, the volume of water thus conducted may be relatively small and the conducting pipes may also be relatively small.

It will be understood without further explanation that the introduction of a small portion of the circulating water into the water jacket near its bottom and at a point remote from the main inlet promotes the movement of the water at all parts of the water jacket, even at that part where there an efiective circulation of'the is secured.

would otherwise not be any flow or current due to the Water circulating means, whereby cooling Water 1 claim as my invention: The combination with aiwater jacketed internal combustion engine having a common Water chamber, of a radiator, a main ater connection from the radiator to the Water jacket, a return Water connection from the Water jacket to the radiator, and

Jficplee cf this patent may be" obtained for .by the circulation of the cooling Water in all parts of the \Water jacket is promoted. This specification signed this 29th day of June, A. D. 1918.
